I'm just curios if anyone has either a graphic, or description of what the stock FD ignition maps look like for both lead and split.

Thanks,

 

Not exactly a stock map but probably close:

I have a couple of questions. What would be the conversion factor for the fuel values used by the Apex to convert them to mS? And does anybody else think that 25 degrees of advance at 8000rpm and 19-20psi of boost is a tad too much?

Do you have information on the car that this was mapped on, the description says intake and catback are the only mods, and that this is how apex ships the units, but dont we all know that this is only a starting point? Also, isnt there supposed to be a stagged injection map for the secondaries?

Im not trying to sound critical of your findings, just being thorough. Oh! and forgot the most important factory, fuel quality!! remember this is from Japan, where they have really good high octane fuel. Id say those values of timing would be ideal using at least 95 octane or better.

 

That did occur to me, I really wasn't looking for fuel maps ign only. I would venture a guess that 19-20 psi is beyond the tuned range of the map.

I am not trying to re create this map on a haltech, just satisfy my curiosity.

 

Well, it doesnt mean you can't, i mean, this would probably work with the right fuel, and probably even make good power. But yes, i understand you're point of view, ive seen some supposed stock FC ignition maps and they look wierder than these.

 

You guys have to remember that the maps were develop using higher octane fuel in Japan and also with the inefficent factory turbos, porting etc. after peak torque at high rpms. It's not a conservative map by all means. Look at the timing they also run at 0 psi at very high rpms just as an example.
You know what they say about base maps. They are just that.

 

Yes and this doesn't take correction maps into account Just looking at this map. I have no idea what they look like (correction maps), or how the PFC, or stock computers actully work. It would be nice to see the actual calcuated advance under normal running conditions. It would also be nice to know how the stock knock sensor comes into play.
